Education: Dr. scient. autumn 1988: The formation of landlocked Atlantic salmon (Salmo salar L.).
Research activities:My research have largely been in salmonid ecology, where I have been working on different species of both Atlantic and Pacific salmonids, much of the activity have been within bioenergetics and life-history variation..
Winter-ecology and energetics of freshwater teleosts in temperate and Arctic areas have scarcely been investigated previously. I have therefore started a series of investigations o ver this theme. Changes in the natural temperature regime (below e.g. hydro-electric plants) transform the conditions for growth of salmonids.
In a number of papers, sea-ranching relevant topics relating to seasonal patterns of migration, growth and survival of anadromous salmonids in northern Norway, have been addressed.
Research projects: In recent years, Berg have been leading or supervising/ participating in : a BioMar and Norwegian Research Council cofunded project: ”Vinterenergetikk hos laks – Effekt av forsammensetning ved lave temperaturer” (Dr. scient. Eldar Å. Bendiksen). He currently leads Wild-salmon project 177954/S40; The sensitivity of different winter survival strategies in juvenile salmon to natural and anthropogenic variation in climate conditions and: Variability among populations of wild and farmed Atlantic salmon – morphology and genetics (NFR – Havbruk)
